description
These quadruple 2-line to 1-line data
selectors/multiplexers are designed for 2-V to
5.5-V V_CC operation.
The ’AHC158 devices feature a common strobe
(G) input. When the strobe is high, all outputs are
high. When the strobe is low, a 4-bit word is
selected from one of two sources and is routed to
the four outputs. These devices provide inverted
data.
The SN54AHC158 is characterized for operation
over the full military temperature range of –55°C
to 125°C. The SN74AHC158 is characterized for
operation from –40°C to 85°C.
